My invention relates to door holding means more especially intended for use on railroad passenger cars, although my improved holder may be employed for holding any door in open position, either against vibration or jarring or against the action of a closure spring, as is readily apparent from the construction hereinafter specifically described. v o, L

The objects and advantages otmy inven tion will be readily apparent from the following description, wherein- Y Figure 1 illustrates a portion of a part1- tion and the end wallet a car and the upper portion of a door, with my improved holding means shown in elevation alnd in door holding position.

Figure 2 is a cross sectional view taken substantially on the line 22r of Figure 1 looking in the direction of the arrows.

Figure 3 is an elevation of the holding element secured to the wall or partition; the view being taken substantially on the line 3-3 of Figure 1 looking in the direction of the arrows. I

Figure 1 is a cross sectional view on an enlarged scale taken substantially on the line l4: of Figure 2 looking in the direction of the arrows. v

Figure 5 is av detail sectional view taken on the line 5-5 of Figure 1.

In the particular exemplitication of the invention, a portion of a side wall or of a- 32LIl3l131OI1 of railroad passenger car isindicated at adjacent to the end wall 11. of the car provided with the usual door, the upper or stile portion whereof is shown at 12 in Figure 1. V i i J vOne portion of. my improved holding means is preferably secured to the upper part of the door-stile and comprises a Suitable bracket 13 secured in any suitable manner, as for example by screws indicated at 14; The bracket is formed to present the two parallel laterally disposed arms 15, 15

arranged in vertical spaced relation, one

proper spaced relation between the jaw ,111l11l)l5 in orderthat the latter may have lateral oscillatory movement and therefore properly function. T

The jaw members 17, 17, which mayhave any suitable configuration generally speaking, areea'ch pivotally held intermediate of the upper and lower arms 15, 15 a'suitable-pin, or for example by a machine screw,

indicated at 18 in Figure 4, which passes through the upper arm 15 and into the lowerv arm 15 at a point, intermediate of theends oi. the jaw members; 1 The outer ends of the jaw members extend av suitable distance for r ward of the arms 15, 15 'of the holding bracket 13 and are preferably curved outwardly as shown at 19, 19; the curvature in connection with the intermediate or pivoted point20 of the jaw members being such as a to provide a socketor pocket at 21-for the purposeof receiving the holding element or bolt secured to the wall or partition of the car and later to be'described; the socket 21. being made to substantially conform with,

the cross-sectional Configuration of the holding element or bolt. The rear or inner ends of the jaw members 17', 17 are shown preferably provided with projecting lips 22 adapted to extend into the slot 16 of the'bracket 13; the projections 22, 22 being preferably employed to assist in guiding the movement and to maintain the jaw members in proper operative position. i

The jaw'members 17, 17, adjacent to the inner ends, are shown provided with the opposing bosses or lugs 23, 23 forthepun' pose of receiving and holding a suitable coil spring 241 which latter normally tends to spread the inner ends of the jaw members apart and therefore to maintain the for-ward outer ends 19 of the jaws under tension and cause the latter to move toward each other. At a suitablepoint on the side wall or partition-10, namely a fixed portion of the car disposed substantially parallel'with the door when the latter is open, I provide a wall plate or bracket 25, which, like bracket 13, may be of any. suitable and desired' configuration and secured firmly; in place by screws 26. The wall bracket/25' is shown provided with an outwardly disposed hollow lug or boss'27' adapted to receive the trunniQn QS extending rear 7 lly rear he tilting latch member er bolt the trailer c tilting movement or oscillation of the latch member from a latching or holding position into an inoperative or non-holding position. The latch member 29'prefcrably comprises an enlarged handle portion 32 disposed at an angle, say of approximately forty-five degrees, to the preferably cylindrical portion 33 which latter is intended to slide into position between the spring controlled jaw members 17, 17 when' the latch member 29 isin holding position. The handle portion v 32 is preferably offset or angularly disposed as shown in Figure 3 and is somewhat enlarged or of greater weight so as to maintain the latch member 29 in. its adjusted positions; the operating or holding position being shown in full lines in Figure 3, while the 'nonholding position is indicated in dotted lines in said figure. The extent to which thelatch member 29 may be oscillated is controlled by the length of the slot 30 in the hollow lug or boss 27 of the bracket plate 25. I

The wall bracket 25 is secured to the wall or stationary partition in a horizontal plane slightly above the horizontal plane of the door bracket 13, so as to dispose the engaging cylindrical portion 33 of thelatch memher into the plane of the jaw members 17, 17, as is clearly evident from Figure 1.

As is apparent from the construction shown and described, when it is desired to 7 hold the door 12 in open position, the latch "jaw'mem'bers 17, 17, with the result that. .When the door 12 is moved into complete member 29 is moved by swinging the handle portion 32 upwardly from the dotted line position shown in Figure 3 toward the opposite side offthe vertical plane of the, axis of the latch member, namely into the full line position shown in Figure 3. hen the latch member is swung into this position, it will bring the latching end 33 into the vertical position shown in Figure 3 where it willbe aligned with a point centrally of the socket formed by the free ends 19, 19 of the open position, the end 33 of the latch mem- .ber will'engage the arcuate ends 19, 19 of the jaw members and cause the later to separate against theaction of spring 2-4; the end'33 ridinginto the socket orpocket 21 of the jaw members. As the jaw members 17, 17 are under constant spring presure, it is apparent that the free ends 19,19 will firmly grasp or hold the portion 33 of the latch member and therefore maintain the door in open position.

Where a latching or holding of the door in open position is not desired, the latch member 29 is then swung into position shown in dotted linesin Figure 3, thus moving the portion 33 out of alignment of the jaw members 17, 17. With the latch member in the position last mentioned, it

will act as a door step or bumper and permit the door to move or swing back into closed position when released.

My invention is especially intended for use on railroad passenger cars and provides means whereby the door is securely held in open position when desired. On the other hand, the latch member may be moved into noii-holding position by the train crew after the train is in motion, thereby assuring closure of the doors while the train is in motion and as a result a chilling or radical reduction in temperature of the caris prevented; while at the same time providing means 'which will firmly hold the doors in open position when desired and preventing pos sible injury to passengers while enteringor leaving the car.

While my improved door holding means is especially intended for use on railroad passenger cars, it is evident that it ma be emplo ed mother situations and the specific embo iment shown and described may be modified in certain respects without, however, departing from the spirit of my invention. r

What I claim is y Door holding means comprising a wall bracket having a laterally disposed hollow boss provided with a circui'nferentially disposed slot, a tiltable latch member having a rearwardly disposed trunnion seated in said boss, a pin in said trunnionjan'd movable in said circumit'erentially disposed slot for holdin the latch member in place and for control ing its degree of oscillation, said latch member being provided with ahandle portion disposed toward one side of the median line of the latch member at an angle less than ninety degrees whereby the latch member is maintained' in its adjusted positions, a door bracket provided with a slot and a pairof vertically spaced arms, a pair of jaw members pivotally mounted between saidarms in spaced relation to move about vertically disposed axes, the rear-ends ofsaid j aiv' members being extended into said j slot with the opposing faces of the jaw members adjacent the rear ends each having a laterally disposed boss, and a coilspring,

the ends whereof are seated on said bosses for'normally forcing the forward ends of the jaw members toward each'other.
